Description

Technical Field

[0001] This utility model relates to the field of transformer coil manufacturing technology, and in particular to a transformer coil impregnation device. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components are the primary coil, secondary coil, and iron core. Transformers can be classified into power transformers and special transformers according to their uses. Power transformers are mainly used in power transmission and distribution lines to change the magnitude of alternating current voltage to meet the needs of different users. A transformer coil is a type of coil that is required for the transformer to operate. During the manufacturing process, transformer coils need to be impregnated with varnish. However, in the current process, the coils are simply placed into liquid for immersion. When the coils are immersed in liquid while stationary, the varnish is difficult to penetrate into the dense winding gaps inside the coil, resulting in uneven insulation layer thickness. Therefore, a transformer coil impregnation device is used to impregnate the coils.

[0003] However, the existing equipment has the following shortcomings: When dipping materials in paint, the existing equipment typically involves workers holding the material hook and placing it into the dipping solution. Prolonged hand-holding by workers can easily cause the material to not fully penetrate the dipping solution inside the material container, resulting in incomplete immersion.

[0004] Therefore, we propose a transformer coil impregnation device to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where it is difficult for workers to fully immerse materials in liquid during prolonged use, and to propose a transformer coil impregnation device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a transformer coil impregnation device, comprising a mounting frame, a material box, a box cover, a connecting column, a material container, and an adjusting device. The material box is fixedly connected inside the mounting frame, the box cover is installed on the upper end of the material box, the connecting column is fixedly connected inside the material box, the material container is slidably connected inside the material box, and the adjusting device is fixedly disposed inside the material box. The adjusting device includes a threaded rod and a limiting block. The limiting block is fixedly connected to the bottom of the material box, the threaded rod is rotatably connected inside the limiting block, and the threaded rod is threadedly connected inside the material container. A rotating block is fixedly connected to the upper end of the threaded rod. A rotating groove is opened inside the upper end of the material box, and the rotating block is rotatably connected inside the rotating groove. A first gear is fixedly connected to the outer surface of the lower end of the threaded rod, and a second gear is meshed with the surface of the first gear.

[0007] Furthermore, a servo motor is fixedly connected to the upper end of the second gear, and a connecting arm is fixedly connected to the surface of the servo motor. By setting the servo motor, the second gear can be rotated, reducing the situation where the second gear is difficult to rotate the first gear during use.

[0008] Furthermore, the connecting arm is fixedly connected to the inside of the material box, and a rotating rod is fixedly connected to the lower surface of the second gear.

[0009] Furthermore, a stabilizing block is fixedly connected inside the material box, and the rotating rod is rotatably connected inside the stabilizing block.

[0010] Furthermore, the surface of the connecting column is provided with an auxiliary component, which includes a hook and a mounting groove. The mounting groove is formed on the surface of the connecting column, and the hook is inserted and connected inside the mounting groove. A connecting block is fixedly connected to the surface of the hook, and a slot is formed inside the mounting groove. By setting the connecting block, the hook can be limited, reducing the situation where the hook is difficult to limit during use.

[0011] Furthermore, a retaining ball is fixedly connected to the side of the connecting block.

[0012] Furthermore, the ball is engaged inside the slot, and a pull ring is fixedly connected to the upper surface of the connecting block.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting an adjustment device, the material box is effectively raised and lowered, which reduces the problem of insufficient material immersion when workers hold the material hook and place it into the immersion solution during the immersion of materials in existing equipment. This is because prolonged hand operation by workers can easily cause the material to not be fully immersed in the immersion solution inside the material box. This adjustment device, through the cooperation of components such as the threaded rod, the first gear, the second gear and the servo motor, realizes the raising and lowering of the material box, which facilitates the equipment to fully immerse the material and improves the practicality of the equipment.

[0015] 2. In this utility model, by setting an auxiliary component, the hook is effectively limited, which plays a role in stabilizing the hook. This reduces the situation where the hook tends to slide on the surface of the connecting column when the existing equipment is in use, making it difficult for the hook to stabilize the material. This auxiliary component stabilizes the hook and improves the stability of the equipment hook. Attached Figure Description

[0023] Please see Figures 1-6 This utility model provides a technical solution: a transformer coil impregnation device, including a mounting frame 1, a material box 2, a box cover 3, a connecting column 4, a material container 5 and an adjusting device 6. The material box 2 is fixedly connected inside the mounting frame 1, the box cover 3 is installed on the upper end of the material box 2, the connecting column 4 is fixedly connected inside the material box 2, and the material container 5 is slidably connected inside the material box 2.

[0024] Mounting frame 1 is welded from high-strength steel, and the overall frame structure has been mechanically optimized with reinforcing ribs and diagonal braces to ensure stability when bearing the full load of material box 2 and material container 5. Material box 2 is a rectangular sealed container made of double-layer stainless steel. The lid 3 adopts a double-layer sealing design, equipped with a high-temperature and chemically resistant silicone sealing ring and a quick-locking mechanism to ensure sealing effect and facilitate quick opening and closing. The connecting column 4 is a cylindrical metal structure with rust-proof surface treatment, used to install hook 71 and assist in material suspension. Material container 5 is a stainless steel container, and its size is adapted to the internal space of material box 2 to ensure smooth sliding, used to hold soaking solution.

[0025] The specific settings and functions of its adjustment device 6 and auxiliary components 7 will be described in detail below.

[0026] In this embodiment: the adjusting device 6 is fixedly installed inside the material box 2. The adjusting device 6 includes a threaded rod 61 and a limiting block 62. The limiting block 62 is fixedly connected to the bottom of the material box 2. The threaded rod 61 is rotatably connected inside the limiting block 62. The threaded rod 61 is threadedly connected inside the material box 5. The threaded rod 61 adopts a high-precision trapezoidal thread design, is made of steel and has undergone heat treatment, and has excellent strength and wear resistance. It is precisely matched with the threaded hole of the material box 5 to ensure the stability of the lifting process. The upper end of the threaded rod 61 is fixedly connected to a rotating block 69. The upper end of the material box 2 has a rotating groove 610. The rotating block 69 is rotatably connected inside the rotating groove 610. The lower end of the threaded rod 61 is fixedly connected to a first gear 63. The surface of the first gear 63 is meshed with a second gear 64.

[0027] Specifically, a servo motor 67 is fixedly connected to the upper end of the second gear 64, and a connecting arm 68 is fixedly connected to the surface of the servo motor 67.

[0028] In this embodiment, by setting a servo motor 67, the second gear 64 can be rotated, reducing the situation where the second gear 64 has difficulty rotating the first gear 63 when the device is in use.

[0029] Specifically, the connecting arm 68 is fixedly connected to the inside of the material box 2, and the rotating rod 65 is fixedly connected to the lower surface of the second gear 64.

[0030] Specifically, a stabilizing block 66 is fixedly connected inside the material box 2, and the rotating rod 65 is rotatably connected inside the stabilizing block 66.

[0031] In this embodiment: the surface of the connecting post 4 is provided with an auxiliary component 7, which includes a hook 71 and a mounting groove 76. The mounting groove 76 is opened on the surface of the connecting post 4, the hook 71 is inserted and connected inside the mounting groove 76, the surface of the hook 71 is fixedly connected with a connecting block 72, and the inside of the mounting groove 76 is provided with a slot 75.

[0032] In this embodiment: by setting the connecting block 72, the hook 71 can be limited, reducing the situation where the hook 71 is difficult to limit when the device is in use.

[0033] Specifically, a retaining ball 74 is fixedly connected to the side of the connecting block 72. The retaining ball 74 is made of spherical rubber.

[0034] Specifically, the ball 74 is engaged inside the slot 75, and a pull ring 73 is fixedly connected to the upper surface of the connecting block 72.

[0035] Working principle: When lifting and lowering the material box 5, the servo motor 67 is activated. The servo motor 67 drives the second gear 64 to rotate. The second gear 64 drives the rotating rod 65 to rotate inside the stabilizing block 66, which in turn drives the first gear 63 to rotate. When the first gear 63 rotates, it drives the threaded rod 61 to rotate inside the limiting block 62. Since the threaded rod 61 is threadedly connected to the material box 5, the material box 5 rises and falls vertically with the rotation of the threaded rod 61. By setting the adjustment device 6, the material box 5 is effectively lifted and lowered, thus achieving the function of lifting and lowering the material box 5. This reduces the problem that in existing equipment, when dipping materials in paint, workers usually hold the material hook 71 and place it into the soaking solution. Prolonged holding by workers can easily cause the material to not fully enter the soaking solution inside the material box 5, resulting in incomplete soaking. This adjustment device 6, through the cooperation of components such as the threaded rod 61, the first gear 63, the second gear 64, and the servo motor 67, realizes the lifting and lowering of the material box 5, facilitating the equipment to fully soak the material and improving the practicality of the equipment.

[0036] When the hook 71 is moved, the user pulls the pull ring 73 to move the connecting block 72 and the retaining ball 74. Then the retaining ball 74 moves out of the retaining groove 75, and the hook 71 is released from the mounting groove 76. By setting the auxiliary component 7, the hook 71 is effectively limited, which plays a role in stabilizing the hook 71. This reduces the situation where the hook 71 is easy to slide on the surface of the connecting column 4 when the existing equipment is in use, making it difficult for the hook 71 to stabilize the material. This auxiliary component 7 realizes the stabilization of the hook 71 and improves the stability of the hook 71 of the equipment.
